The pevent_parse_event() routine will parse a events/sys/tp/format file
and add an event_format instance to the pevent struct.
This patch introduces a pevent_parse_format() routine with just the bits
needed to parse the event/sys/tp/format file and just return the
event_format instance, useful for when all we want is to parse the
format file, without requiring the pevent struct.

perf defines both __used and __unused variables to use for marking
unused variables. The variable __used is defined to
__attribute__((__unused__)), which contradicts the kernel definition to
__attribute__((__used__)) for new gcc versions. On Android, __used is
also defined in system headers and this leads to warnings like: warning:
'__used__' attribute ignored
__unused is not defined in the kernel and is not a standard definition.
If __unused is included everywhere instead of __used, this leads to
conflicts with glibc headers, since glibc has a variables with this name
in its headers.
The best approach is to use __maybe_unused, the definition used in the
kernel for __attribute__((unused)). In this way there is only one
definition in perf sources (instead of 2 definitions that point to the
same thing: __used and __unused) and it works on both Linux and Android.
This patch simply replaces all instances of __used and __unused with
__maybe_unused.

If memory allocation for handler fails or argument type is not match,
return gracefully instead of calling die(). Also add an new error code
for the later case.

The pevent_strerror() sets @buf to a string that describes the
(libtraceevent-specific) error condition that is passed via @errnum.
This is similar to strerror_r() and does same thing if @errnum has a
standard errno value.
To sync error string with its code, define PEVENT_ERRORS with _PE()
macro and use it as suggested by Steven.

Define and use error numbers for pevent_parse_event() and get rid of
die() and do_warning() calls. If the function returns non-zero value,
the caller can check the return code and do appropriate things.
I chose the error numbers to be negative not to clash with standard
errno, and as usual, 0 for success.

Since the __print_hex() function is used in print fmt now, add
corresponding parser routines. This makes the output of perf script on
the kvm_emulate_insn event not to fail any more.
before:
kvm_emulate_insn: [FAILED TO PARSE] rip=3238197797 ...
after:
kvm_emulate_insn: 0:c102fa25:89 10 (prot32)

As libtraceevent will be a library, having struct record is far
too generic of a name to use. Renaming it to be consistent with the
rest of the functions will be a better long term solution.

libtraceevent library prints out in usecs but perf wants to print out
in nsecs. Add a flag that lets the user decide to print out in usec
or nsec times.

Some of the util functions of libtraceevent.a conflict with perf,
such as die(), warning() and others. Move them into event-util.h
that is not included by the perf tools.
Also, as perf compiles with 'bool' the filter_arg->bool needs to
be renamed to filter_arg->boolean.

Copy over the files from trace-cmd to the Linux tools directory
such that applications like perf and latencytrace can use the
more advanced parsing code.
Because some of the file names of perf conflict with trace-cmd file
names, the trace-cmd files have been renamed as follows:
parse-events.c ==> event-parse.c
parse-events.h ==> event-parse.h
utils.h ==> event-utils.h
The files have been updated to handle the changes to the header files
but other than that, they are identical to what was in the trace-cmd
repository. The history of these files, including authorship is
available at the git repo:
git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git
The Makefile was also copied over, but most of it was removed to
focus on the parse-events code first. The parts of the Makefile for
the plugins have also been removed, but will be added back when the
plugin code is copied over as well. But that may be in its own
separate directory.
